Space weather describes variations in the environmental conditions within the solar system, with particular attention to the space near the Earth. Magnetic fields, radiation, and plasma, which have been ejected from the Sun, can interact with the Earth’s upper atmosphere and surrounding magnetic field causing a variety of physical phenomena including geomagnetic storms and substorms, energization of the Van Allen radiation belts, and aurorae. Space weather has been widely studied not only for the fascinating phenomena that can be observed on or near planets but also for its deleterious effects on space instrumentations.
This Collection includes original research manuscripts on the topic of space weather, the underlying mechanisms of solar physics that influence these phenomena, and also the topics of planetary space weather and interplanetary phenomena.
